That WG has blown diaphragm, dissassemble and replace it. Car will overboost otherwise.

Some air will always go past the valve stem and into exhaust tube, no problem. But no gas should go between top vent and the bottom vent. There is a membrane in-between, probably ruptured.

Be careful when dissassembling, there is substantial spring-force involved. Use vice or something else to prevent the bell flying once last bolt has been undone.
Thank you for your time,
